Title: Optical recording medium
Inventor: MORIMOTO YASUAKI
IPC: G11B13/04
Filed: 1996-01-18
Abstract: Optical-recording medium having a light-transmitting substrate layer. 
<??>CDs are such recording media, on which data are stored in so-called pits, that is to say depressions in a light-reflecting layer following the light-transmitting layer. In the case of magneto-optical discs, data are stored in a magneto-optical layer by magnetising in the one or the other direction of magnetisation. For reading the data stored in this way, use is made of the Kerr effect, which produces a measurable rotation of the polarisation plane when a linearly polarised light beam is reflected at the magneto-optical layer. Although both recording media - CD and magneto-optical disc - already have a high storage capacity, a considerable increase in the storage capacity is of great benefit, in particular for computer applications and as a video disc. 
<??>In order to increase the storage capacity considerably, the light-transmitting substrate layer (1) is followed by a light-reflecting magneto-optical layer (2), in which data can be stored on the one hand by magnetising and on the other hand by means of depressions (3), so-called pits. The light-transmitting substrate layer (1) may also be followed by a partially transmitting magneto-optical layer (2) without pits (3), which is then followed by a light-transmitting layer (10). In this or a following layer (11), data can be stored by means of pits (3). 
<??>Storage medium for computers, video disc, CD.

Title: Production of expanded rubber composition and pneumatic tire containing the same
Inventor: TAKESHITA MICHITAKA
IPC: C08J9/04
Filed: 1988-01-01
Abstract: PURPOSE:To obtain an expanded rubber composition having closed cells and stabilized in running performances on a frozen or snowed road surface, by vulcanizing rubber composition containing a blowing agent and a blowing aid coated with a specified film by heating and thereby melting the film to allow the blowing agent to react with the blowing aid and to expand the rubber composition. CONSTITUTION:A slurry formed by dispersing a blowing aid (e.g., salicylic acid) in a solution formed by dissolving 5-80wt.% hydrophobic film-forming agent (e.g., syndiotactic 1,2-polybutadiene) in a solvent is spray-dried to obtain a blowing aid of a mean particle diameter of 0.5-250mu, surface-coated with a heat-meltable film. Common rubber additives, a blowing agent (e.g., azodicarbonamide) and said blowing aid are added to a rubber component, and the resulting mixture is kneaded, molded and vulcanized by heating in a mold, whereupon the film with which the blowing aid is coated is molten to allow the blowing agent to react with the blowing aid and to expand the rubber composition.

Title: Improvements in or relating to the manufacture of fumagillin
Inventor: GOODALL ROBERT ROTHES
Filed: 1953-01-07
Abstract: Fumagillia is isolated from a fumagilliacontaining biologically manufactured crude obtained by extraction from a fermentation broth, by distributing the crude solids between an aqueous solution at pH higher than 7 and lower than 12 and an organic solvent which is (a) inert, (b) not miscible in all proportions with water and (c) is capable of dissolving the said crudes.  Specified are esters of aliphatic alcohols containing not more than 9 carbon atoms especially ethyl acetate, butyl acetate, amyl acetate, ethyl propionate and amyl lactate; halogen derivatives of hydrocarbons especially ethylene dichloride and trichlorethylene; aromatic hydrocarbons especially benzene, toluene and chlorbenzene.  In general, the solvents contain two or more of the elements carbon, hydrogen, oxygen, chlorine, bromine and iodine and possess a dielectric constant at 20 DEG  C. above 2.2 and below 10.  The weight concentration of the fumagillia containing solids in the organic solvent should not exceed 5 per cent.  The aqueous solution is preferably buffered especially with sodium hydroxide, boric acid and potassium chloride in which the concentration of boric acid does not exceed 30, and preferably 10, grams per litre.  The prepared pH of the aqueous solution is pH 8 to 10.  The aqueous solution of fumagillia so produced is acidified to pH 5.0, extracted with an organic solvent, e.g. chloroform, the solvent removed and the residue crystallised from e.g. acetone, which is preferred.  It is preferred to extract a filtered fermentation broth with the same solvent as is used in the distribution separation; in which case, the extract so produced is treated directly with the aqueous phase.

Abstract: 1300614 Mixing liquids NOLL MASGHINENFABRIK GmbH 5 Jan 1970 [28 Jan 1969] 490/70 Heading B1C [Also in Division F1] Mixing of liquids, e.g. beverage syrup and water, is achieved by passing one liquid under pressure through a pressure nozzle 2 into a mixing tube provided with a receiving nozzle 6 and a diffuser portion 7 and which is spaced from the nozzle 2 to form a suction chamber 11 to which other liquids are supplied. The exit orifice of the pressure nozzle 2 is unobstructed; liquid enters the nozzle through openings which are shown as radial bores 2b, Fig. 1 (not shown). The pressure nozzle is axially adjustable relative to the receiving nozzle and means are provided to indicate the spacing between the two nozzles. By varying the distance between the nozzles the quantitative ratio between the liquid fed under pressure and liquid drawn into the suction chamber is varied. In the apparatus shown a pump 41 delivers liquid from an accumulator 47 in which it is degassified by a vacuum pump 45, through a flow gauge 37f to a shut-off valve 36 which, in common with shut-off valves for liquids to be admixed, is controlled by compressed air from a solenoid 40 operating in unison with the pump 41. Liquids are drawn into the suction chamber through adjustable throttle valves 38. In a modification the receiving nozzle is adjustable within the housing 1.

Title: Antennas
Inventor: BERKOWITZ BERNARD
IPC: H01Q3/14
Filed: 1958-01-06
Abstract: 840,281. Aerials. SPERRY RAND CORPORATION. Jan. 6, 1958, No. 535/58. Class 40 (7). A scanning aerial system consists of a fixed lens of thick annular shape having a radiallyvarying refractive index and a primary element capable of angular movement and disposed adjacent the inner curved wall of the lens in such a way as to be capable of directing radio energy into the lens. Preferably the primary element is capable of full 360 degrees rotation. In one embodiment the rotating part of the structure consists of a circle of waveguide 12 having a plurality of slots 17 in its broad outer wall 18 forming the primary elements of the system. The waveguide 12 is supported by a spider 19 from a central bearing and may be driven round by scanning mechanism 21. The feeder comprises a radial waveguide 22 leading to a rotating joint 24. Round and closely adjacent to the wall 18 is positioned the inner circumferential boundary of the lens 11. The lens is formed of a pair of parallel metallic plates 13 and 14 and a dielectric member 15 disposed between them. The transverse area of the dielectric member decreases with increasing radius so that the effective refractive index (y) of the lens varies with radius (r) in accordance with the equation :- The lens is provided with a dielectric cover 25 and an air-tight cover 26 protects the moving parts of the system. In the design of the aerial system the various factors necessary to give a planar wavefront have to be carefully considered. Apart from the graduation of the refractive index referred to above it is necessary to position the slots 17 so that the phase of the energy passing through each is correct. The way in which this can be done is discussed in the Specification with reference to Figs. 3 to 5 (all not shown). The amplitude distribution across the aperture of the system is under the control of the designer and can be varied by varying the contribution of each slot to the total energy radiated or received. A discussion on the relationship between the energy distribution across the aperture and that at the slot array is given.
